Hair device



Patented Oct. 3, 1939 UNITED STATES PATENT OFFICE Claims.

This invention relates to a hair device and has relation more particularly to an apparatus particularly designed and adapted for use in straightening hair, and it is primarily an object '5 of the invention to provide such an apparatus combining the use of heat together with intermittent pressure.

Another object of the invention is to provide an apparatus of this kind comprising a base member constructed in a manner to permit the same to closely approach the scalp and which is provided. with means for effectively holding thereon the hair to be treated and wherein said base member is provided with means for heat- 1 ing the hair being treated and also for imposing pressure thereon.

The invention also has for an object to provide an apparatus of this kind-including a base member carrying hair treating elements, said base member being of a formation to permit the same to be closely positioned adjacent to the scalp together with means for supporting the base member in a manner whereby the base member may be readily and quickly adjusted into a position with respect to the head of a person best suited to facilitate the treating of "the hair.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved hair device whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter 35 more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the 40 same with reference to the accompanying drawing, wherein:

' Figure 1 is a view in side elevation of a hair straightening apparatus constructed in accordance with an embodiment of my invention, cer- 45 tain of the parts being in fragment;

Figure 2 is an enlarged detailed sectional view taken substantially on the line 2--2 of Figure 1;

Figure 3 is a view in bottom plan of the base member as herein employed;

50 Figure 4 is a horizontal sectional view taken through the reciprocating hammer as herein employed;

Figure 5 is a fragmentary detailed sectional view taken substantially on the line 5--5 of Fig- 55 ure 3.

As illustrated in the accompanying drawing,

B denotes an elongated base member of desired dimensions and which is disposed longitudinally on a curvature to facilitate the close positioning of a longitudinal marginal portion of the base member to the scalp of a person. This approach of the base member with respect to the scalp is at the inbow or concave side thereof and for which reason said side portion of the member B is bevelled, as at I, so as to reduce to a minimum any contact between the base member and the scalp and also to faciltate any slightrocking or turning adjustment of the base member B in a direction transversely thereof as may be of advantage during the time the apparatus is being used.

This base member B may be made of any material which will properly meet the requirements of practice and the margins thereof are preferably defined by a depending flange 2. This base member B at a point preferably to one side of its longitudinal center has a portion raised to provide an anvil 3, the top surface of which is, as herein disclosed, flat and smooth. This anvil 3 is so formed to provide an internal chamber 4 in which is arranged an electric heating unit 5 of any desired type. This unit 5 is adapted to have proper connection with a suitable source of electrical energy through the medium of the conductors 6 which extend up through an opening I provided in the end portion of the base member B remote from the anvil 3.

Secured along a side marginal portion of the anvil 3 and extending a desired distance thereabove is a comb member 8 and which member 8 is at the outbow or convex side of the member B. This same side portion of the member B below the comb member 8 carries a suitable hair clamping medium 9. As this clamping medium may be of any type or character as preferred it is believed unnecessary that a detailed description and illustration thereof be given other than to state that after the base member B has been properly positioned with respect to the head the hair to be straightened is disposed transversely across the anvil 3, engaged with the comb 8 and then folded downwardly to be clamped to the side marginal portion of the base member B.

Adjacent the inner end of the anvil 3 the base member B is provided with the upstanding pedestal l0 formed to provide a vertically disposed guide sleeve H through which is freely but snugly directed a rod l2 of desired length. Above the sleeve H the pedestal I0 is formed to provide a horizontal bearing l3 in which is rotatably mounted a shaft l4. As herein disclosed, this shaft" l4 has fixed thereto for rotation therewith a disk I5 operatively engaged through the medium of the rigid link I6 with the upper end portion of the rod l2 whereby upon rotation of the shaft M the rod [2 will be caused to reciprocate and, of course, at a speed of reciprocation depending upon the speed of rotation of the shaft M. This shaft M, as herein disclosed, has suitably coupled thereto a flexible shaft, generally indicated at H, which in turn is adapted to be operatively driven from any preferred or convenient source of power. As this source in itself forms no part of the present invention it is not believed that a detailed description and illustration thereof is required.

The rod I2 is positioned above the central portion of the anvil 3 and the lower extremity of this rod l2 carries a hammer IS the under or working surface of which is flat and smooth and of an area substantially equal to the area of the working or upper surface of the anvil 3. These faces or surfaces of the anvil 3 and hammer l8 are parallel so that efiective' treatment of the hair disposed over the anvil 3 is assured.

This hammer I8 is hollow and has suitably arranged therein an electric heating element l9 of any particular type which element I9 is also in communication with a suitable source of elec trical energy through the conductors 20. It is to be noted that these conductors 20 offer no hindrance or obstruction to the desired reciprocation of the rod l2 and the hammer 18,

In the straightening of hair it has been fully demonstrated that both pressure and heat are required in order to obtain the most desirable results and it has also been fully demonstrated that the pressure is more effective when intermittently applied. This intermittent application of the pressure is assured by the provision of the reciprocating hammer l8 and, of course, the heating elements 5 and I9 assure the anvil 3 and the hammer l8 being of a sufficiently high temperature to provide desired heat.

It is also to be stated that the stroke of the rod I2 is such as to bring the under or working face of the hammer l8 to just about the point of contact with the upper or working face of the anvil 3 so that it is assured there will be no disastrous crushing action upon the hair.

Rigidly secured to an end of the base member B and preferably at the end thereof adjacent to the pedestal I9 is an elongated rod 2|, an intermediate portion 22 of which is formed to provide a certain degree of flexibility whereby the operator can more effectively adjust the base member B during a hair treating operation.

The outer end portion of this rod 2! is slidably disposed through a sleeve 23 and this rod 2i is locked in desired selected longitudinal adjustment with respect to the sleeve 23 through the medium of the binding screw 24 threading through a wall of the sleeve 23 for proper contact with the rod 2|. The central portion of the sleeve 23 has a universal connection, as at 25, with an upstanding post 26. This universal connection 25 permits further ready adjustment of the base member B in any direction as the working requirements may necessitate. The post 26 is to be supported in a vertical position in any manner as may be the best suited and, therefore, any supporting means for this post it is not necessary to describe or illustrate other than to state that this post 26 is preferably supported in any of the already well known ways which allow for a selective vertical adjustment of the post.

While not at all times necessary, I prefer to provide a closure plate 2'! to be engaged with the base member B for concealing the interior thereof, and to facilitate the application of this plate 21 the inner lower corners of the flanges 2 are rabbeted, as at 28.

As is illustrated in Figure 4, the hammer 18 has a removable end plate 29 to facilitate the application or removal of the heating element I9.

From the foregoing description it is thought to be obvious that a hair device constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
